Function and Applications
Forged Single Flange Wheels are designed to guide rail-mounted equipment along tracks, providing lateral stability in one direction while allowing flexibility for curved or complex rail systems. Their single flange design is ideal for applications with consistent track conditions, minimizing maintenance and ensuring smooth operation. Commonly used in:

· Cargo Trains: Supporting freight wagons for heavy loads like coal, ore, or containers, with capacities up to 50 tons per wheel.

· Sugar Plants: Powering transfer carts and kilns handling abrasive or high-temperature materials.

· Port Machinery: Enabling rail-mounted cranes and container shuttles in port logistics.

· Mining Operations: Facilitating mine carts and rail-based transport in underground or surface mines.

· Industrial Facilities: Used in steel mills, cement plants, and other heavy industries for material handling.

WALKSON’s single flange wheels are engineered to withstand high loads, corrosion, and wear, making them a cost-effective choice for reliable rail performance. Contact us at info@walkson.com (mailto:info@walkson.com) to discuss your specific needs.

Material Grades (EN and ASTM Standards)

WALKSON selects premium forged steel grades to ensure durability, strength, and resistance to wear and fatigue. Commonly used materials include:

· EN Standards:

· S355J2 (EN 10025): A high-strength, low-alloy steel for general-purpose heavy-duty wheels.

· C45E (EN 10083): A medium-carbon steel offering balanced strength and machinability.

· 42CrMo4 (EN 10083): A chromium-molybdenum alloy steel for high-load, wear-resistant applications.

· ASTM Standards:

· AISI 1045 (ASTM A29): Equivalent to C45E, providing excellent toughness for rail wheels.

· AISI 4140 (ASTM A29): Equivalent to 42CrMo4, ideal for high-stress environments like port machinery.

· AISI 4340 (ASTM A29): A high-strength alloy for extreme conditions in mining or freight trains.

Material selection is based on application-specific factors like load, environmental exposure, and wear resistance. WALKSON provides material certification per EN 10204 3.1 or 3.2 standards upon request, ensuring traceability and compliance.

Modern and Standardized Manufacturing Process

WALKSON employs a cutting-edge manufacturing process for Forged Single Flange Wheels, adhering to international standards at every stage:

· Material Sourcing: High-quality steel ingots are procured from certified suppliers, verified for chemical composition and purity.

· Forging: Hot forging at 1,100–1,250°C using hydraulic presses (up to 10,000 tons) to create a dense, uniform grain structure for superior strength.

· Standard: ISO 6892-1 (tensile testing), ASTM E8/E8M.

· Heat Treatment: Normalizing, quenching, and tempering to achieve optimal hardness (HB 229–269 for 42CrMo4) and toughness.

· Standard: EN 10083-3, ASTM A29.

· Machining: CNC lathes and milling machines ensure precise flange profiles, wheel diameters, and surface finishes (Ra 3.2 or better).

· Standard: ISO 2768 (tolerances), ASME Y14.5 (GD&T).

· Surface Treatment: Optional induction hardening (HRC 50–55) or anti-corrosion coatings (e.g., zinc-rich primer) for enhanced durability.

· Standard: ISO 12944 (corrosion protection).

· Inspection: Rigorous quality checks using advanced equipment (detailed below).

Our ISO 9001:2015-certified facilities ensure consistent quality and traceability. We comply with EN 13262 (railway wheels) and ISO 6506 (hardness testing) for rail-specific standards.
